Local corrections stored as crs: structures (MaskGroupBasedCorrections and the older
gradient / circular gradient / paint containers) become our masks: linear and radial
gradients, brushes (dab runs → strokes), Subject / Sky, luminance and depth ranges, with
add / subtract / intersect and invert, and all local sliders. lightcraft-meta's XmpData gains
`values`, a structured view of every property (arrays of structs survive); .lrtemplate Lua
tables convert into the same shape.
Applying a preset adds its masks to the photo's own (once; Amount scales them); sidecar masks
replace them and radial masks are fitted to the photo's aspect. Unsupported components
(colour range, other AI selections) are reported as "Mask: <kind>".

preset.import (File ▸ Import Presets…, Presets panel ⋯, drag & drop, CLI, MCP) now reads
everything people actually download or carry over from other editors:
- classic .lrtemplate files (Lua table literal parser; value.settings uses crs: field names),
including old process-version fields (Exposure, Contrast, FillLight, HighlightRecovery,
Shadows, Brightness, Clarity, ToneCurve) approximated with today's sliders;
- photos carrying their edits in XMP ("DNG presets" from mobile apps, edited JPEG/TIFF): the
look only, without the photo's crop, geometry or custom white balance;
- .zip bundles (stored + deflate) of any of these, skipping __MACOSX / hidden files;
- folders: the pack's folder name becomes the group, skipping app/format container folders
("Lightroom Classic", "XMP", "Mobile (DNG)"…).
Each imported preset reports the settings that had no counterpart (`unmapped`: profiles,
looks, local masks); the app's toast names them. dryRun previews, group overrides.
Dropped .lcpreset/.lrtemplate/.xmp/.zip files import as presets instead of photos.

curve.refineSaturation (0..100, default 100 = the curve's own saturation): after the tone
curves, the chroma around luma is rescaled so saturation moves from the curve's towards the
pre-curve value, keeping the curve's tone. CPU (finish::refine_saturation) and GPU twin,
equivalence case, slider under the curve editor, crs:CurveRefineSaturation import.

White-preserving primaries matrix (OkLCh hue rotation / chroma scale of each Rec.2020
primary) plus a luminance-preserving green/magenta shadows tint, applied in scene-linear
light before the tone map. CPU (colorops::calibrate) and GPU (finish.wgsl) with an
equivalence case; seven control specs (calibration.*), a settings group, crs: import
(ShadowTint, Red/Green/BlueHue/Saturation) and a Calibration section at the bottom of the
Edit panel.
